A CORPORATION OF WEST VIR- DUMP-CAR.

Specification of Letters Patent.

Be it known that I, FRANK' S. iIneonnsr, a citizen of theUnited States,.residing at St. Louis, State of Missouri, have invented -a certain newand useful Improvement in Dump-Cars, of which the following is a full,clear, and exact description. reference Y being had to the accompanyingdrawings.

The object of this inventionisto provide very simple and eilectivemechanism for raising the doors of dump cars.

The invention is well adapted for cars of the Ingoldsby type,`whereinthere is a longitudinal center member to which are hinged dumping doorswhich form all or a portion of the load carrying floor of the car andswing downwardly at-Atheir4 outer edges-to discharge the load. Insuchcars it has been customary to support vthe doors by means of hookspivoted along the side of the car and engaging floor beams on the undersides of the doors, the upper ends of these hooks' being connected witha pivoted operating lever, whichV is thrown in one direction to- ,causethe hooks to engage and in the opposite direction-to release them. Ihave discovered that this same operating lever may be used to operate amechanism to raise the doors.' y vSuchan arrangementiis' the s ubject ofthe present application.

- This invention includes broadly the combination of releasingmechanism, raising mechanism and a common operating member therefor. Itincludesmoreover the particular embodiment shown in the drawings andhereinf after more fully described, thou h -it is to be understood thatnumerous m iiicationsA of this embodiment may be'. made Withoutdeparting from my invention'. i In the drawings, Figure 1' is a sideelevation of substantially half a. car embodying my invention; Fig. 2 isa cross section thereof; Fig. 3 is an end view; figs. 4 and 5 aredetails, being vertical sections `substantially on thecorrespondinglynumbered lines of Fig. 1.; Fig. 6 is a detail'ofraslightly modified form of pulleywhich may be employed in the raisingmechanism. f y

Referring' to thepartsjby reference nu-l morals, 10 represents theside-of a car which is shown as a plate girder, having ya lower.

" chord 18, an upper chord A,i9 and vertical tion shown in Fig. 1extending in the direc- Application-filed A11-gust 24, 1907. Serial No.339,939.

stilieners 17; 11 represents the central longitudinal member, which isshown as ridgeshaped, and 12 the dumping doors hinged to the centrallongitudinal member, and adapti ed to extend outwardly to the car sides.13 represents` 'an inclined end oorand 14 a' cross beam orv a member.The car shown is thus divided into four hoppers, and the load isnormally supported by the dumping doors and the inclined walls of thesehoppers.

It is to be understood that the present invention is not concerned withtheinterior of the car, which may be made in hoppers as illustrated, ormay be a level bottom car wherein the doors constitute substantially thewhole of the bottom, or it may be constructed in other form.

l Pivoted to the sides ofthe car are hooks or levers 20, the .lower endsof which are adapted to engage beneath floor beams 21 on the under sidesof the doors. The upper ends of these hooks are connected by a horiezontal bar 22.1which is connected by a link 23 with an operating lever24. This lever is pivoted at' a lsuitable point, the arrangement shownVbeing by means of a bracket 25 secured to the end strut 26 of .thegirder side.

The pivoting may be made directly to the.y i

car side, or in any other manner desired.

vIt will be seen from the structure described, that, when t-he lever isin the position toward the extreme end of the car, the hooks engagebeneath theyloor beams and support the doors. When the lever is thrownforward the books are withdrawn from the floor beams and the doorsdropped. This isV the usual arrangementin I-ngoldsby cars. i v

To raise the doors I provide the follo'wing very simple mechanism:Secured tov each door are two or more cables, chains or flexi blemembers indicatedl by 30. These flexible members pass upwardly oversuitable pulleys 31 and then extend horizontally toward the end of thecar. These pulleys 31' are so formed as-to carry also a longitudinal bar32, which (as shown in Figs. L5) may be in Athe form of a channel-bar,with its flanges facing downwardly. The upper ends These teeth may bemade ina solid bar 34 extending withinand secured to the channel U32.Pulleys 57, s`imilar to pulleys 31 are v.provided at close intervalsbeneath the tooth lbar 34, to effectively support it.

In the vpresent invention, the operating liever'24 extendsbelow itspivot 25 and' to :such extension is pivoted, an operating pawl jfteeth 33.l 36 4represents a detent pawl verrtending cross-wise of .the car, andadapted to engage the teeth 33. This detent pawl-is Vshown as being,pivoted to a'bracket `37 se` curedto the channel beam '16 vwhich.constituteSf-an, extension of .theside-sill. The

v,pa'wl. 361 rests against the outer face of the vertical strut 26.' d dY Now, with the abovedescribed construction, if the doorshave beendropped to discharge theload, they may be easily elevated byoscillations of the operating lever 24. AThe forward inovement of theupper` end of'that 'lever towardthe center of the car. shoves thebar`v32 toward the -end ofthe car, drawL .ing upwardly on the cables andelevating the door. At the end of the stroke the gain made is secured bythe detent pawl 36, the inner end of which is drawn upward `by theoperators foot, so lthat the pawl-nose engages the teeth 33 andvprevents backward movement of the longitudinal bar. As the lever ismovedbackward, the pawl 35 clicks idly over the teeth 33; then, `on thenextstroke, the door is further elevated, and so on, by successiveoscillations until the door lbeams slightly and" brings the doors snuglyinto position. ,'This same movement releases the-tension on the iexiblemembers which releases the pressure on thel detent pawl 36.

'As soon as the operator removes his .foot

from ,beneath this pawl, the superior weight of its inner end swingsthis 'end downward whlch raisesv the rear end of the pawl 35 extendingabove the detent pawl, thus freeing to the doors.

the raising mechanism. The parts thus automatically assume position forthe next releasing of the doors, as soon as the'doors have been raisedand locked.

If desired, suitable guide pulleys 40 may be provided tor the exiblevmembers 30 to bend against in passing from the pulleys 31 In thedrawings these pulleys are,..shown as mounted in suitable brackets 4lriveted to the lower chord 18 on car side.

' In Figs. 1,-5 I have shown the pulleys 31 as being journaled on bolts'43 mounted in brackets 44 riveted to the car side. I`his constructionmay be employed where 1t 1s desirable, to locate the longitudinal bar 32outside of the stiieners 17 or other members ofthe car. In some forms ofcar, however, it may be desirable to locate this member closer to thecar side, in which case the pulthem and being formed with an eye 50extending around a bolt 51, connecting the bars ,32. Whether the pulleyand longitudinal -member take the form shown in Fig. 4 or Fig. 6 dependson the convenience of construction. In either event space is providedfor the cable, and flanges 55 are provided by the pulley for guiding thelongitudinal member.
